Title: Migrant networks and job search outcomes: Evidence from displaced workers
<br/>
<br/>Authors: Colussi, Tommaso
<br/>
<br/>Abstract: This paper investigates how the job search outcomes of displaced migrants are affected by the labor market outcomes of past co-workers of the same nationality. For this exercise I use matched employer-employee micro data on the universe of private-sector employees in Italy between 1975 and 2001. The analysis shows that a 10 percentage point increase in the network employment rate raises the re-employment probability within 36 months after job loss by 5.7 percentage points. The paper also sheds light on the different mechanisms generating the social effect and it highlights the role of migrant networks in explaining immigrant segregation.The cost of segregation in social networkshttp://hdl.handle.net/10419/97360
Title: The cost of segregation in social networks
<br/>
<br/>Authors: Allouch, Nizar
<br/>
<br/>Abstract: This paper investigates the private provision of public goods in segregated societies. While most research agrees that segregation undermines public provision, the findings are mixed for private provision: social interactions, being strong within groups and limited across groups, may either increase or impede voluntary contributions. Moreover, although efficiency concerns generally provide a rationale for government intervention, surprisingly, little light is shed in the literature on the potential effectiveness of such intervention in a segregated society. This paper first develops an index based on social interactions, which, roughly speaking, measures the welfare impact of income redistribution in an arbitrary society. It then shows that the proposed index vanishes when applied to large segregated societies, which suggests an asymptotic neutrality of redistributive policies.Behavioral implications of shortlisting procedureshttp://hdl.handle.net/10419/97359
Title: Behavioral implications of shortlisting procedures

<br/>Abstract: We consider two-stage shortlisting procedures in which the menu of alternatives is first pruned by some process or criterion and then a binary relation is maximized. Given a particular first-stage process, our main result supplies a necessary and sufficient condition for choice data to be consistent with a procedure in the designated class. This result applies to any class of procedures with a certain lattice structure, including the cases of consideration filters, satisficing with salience effects, and rational shortlist methods. The theory avoids background assumptions made for mathematical convenience; in this and other respects following Richter's classical analysis of preference-maximizing choice in the absence of shortlisting.What do VARs tell us about the impact of a credit supply shock?

<br/>Abstract: This paper evaluates the performance of structural VAR models in estimating the impact of credit supply shocks. In a simple Monte-Carlo experiment, we generate data from a DSGE model that features bank lending and credit supply shocks and use SVARs to try and recover the impulse responses to these shocks. The experiment suggests that a proxy VAR that uses an instrumental variable procedure to estimate the impact of the credit shock performs well and is relatively robust to measurement error in the instrument. A structural VAR with sign restrictions also performs well under some circumstances. In contrast, VARs of the narrative variety, i.e. VAR models that include measures of the credit shock as endogenous variables are highly sensitive to ordering and measurement error. An application of the proxy VAR model and the VAR with sign restrictions to US data suggests, however, that the credit supply shock is hard to identify in practice.
